Sounds like cheating to me rather than a computer fault?

If u don't know leave it. May I remind u that this is a help room.
I hope this is now clear to u all nuts...

Bravo to those who understand this situation even though they can't help.

Those who can help I thank you in advance cheers.

However, I have found a solution to the 1st question so don't bother with it.

Regards
